SOLDERING IRON.

Application fi1ed-February 6, 1923. Serial No. 617,411.

To all whom it may concern:

Be it'known that I, VVALTHER BURsTYN,

a citizen of Germany, residing at Berlin, Prussia, Germany, have invented a new and useful Soldering Iron, of which the following is a specification.

My invention relates moreparticularly to soldering irons in which a flame of gas is '11Sd to heat continuously the copper piece. 'Hithertogas mixed with air hasbeen burned in such soldering irons, the mixture being produced either by an injector (Bunsen burner) or by means of-an air blast.

According to the presentinvention a very simple and eflective soldering iron is produced by the use of a special burner which has remarkable advantages in comparison with the above mentioned burners. burner is fed byordinary gas and the flame is made hot .and eflective by its special shape hithertonot used for heating purposes.

WVhen pure gas burns out of a round hole a longish pointed flame is obtained which. isbright, sooty and not very hot if the diameter of the hole surpasses acertain small.

size :corresponding to a consumption of about 10 litres of .gas per hour, assuming that-agasof usual pressure and composi-' Etion is employed. But it -.means are provided to produce a thin, flatand approximately semi-circular flame likethe flames in ordinary acetylene lamps the flame is unp I V I -lng 1rons a number ofburner t1ps have to :be used being placed sufliciently ap artfrom der the same conditions non-luminous and very hotup to a consumption of 50-or 80 litres per hour, according to the pressure and composition of the gas. This effect is due to the thin shape of the flame which offers to the air a relatively large surface, thereby producing favourable conditions of combustion.

The object of the present invention is a soldering iron fitted with one or more burners producing a flame of the described shape. Two-hole burners such as are used for acetylene are preferably used for this purpose.

In the accompanying drawing, Figures 1 and 1 are, respectively, a side elevation and a vertical section of a burner tip embodying the invention;

elevation of a slightly vmodified torm of iron with three burner openings;

Figs. 4: and 4 are similar views ofa fur-- their modification with six burner openings; an

Fig. 5 is a fragmental side elevation of .a-st ill further modified form of iron.

R'eferring to Fig. 1, there is illustrated one of the tips .7), preferably made of soap stone. The gas comes outof two tiny holes 0m,the two gas jets hitting one another at -is held. The advantage compared with a soldering iron using compressed a1r lieslalso in thelgreater simplicity of construction,

and in thefaet that the air blastplant is dispensed with and that the heat of the flaniejis .better utilized owing to the rela tivelynsmall speed ofthe'flame gases consequentlyhaving more. time to supply their heat to the copper piece.

. One simple flame as described is suflicient for light soldering irons; for heavier soldereach other.

In Figs. 2-5 70 represents the copper piece of the soldering iron, I) a burner top made of soap-stone or metal, p the burner in which one or several burner tips are cemented, t a metal gas tube serving at the same time as handle to the soldering iron and as passage for the gas which is conducted to it by a flexible tube 0, usually made of india rubber.

Fig. 2 shows a small soldering iron in form of a hammer with one single flame. The copper piece 70 is cylindrical and its front is chisel-shaped. It is fixed to the burner p by means of a support 71. An asbestos-washer a lessens diversion of heat. Gas tube 2? is-screwed into the burner p and is mounted on its other end with a piece 1- for the india rubber tube 6. A wooden handle I is fi ed n h ga tube.

A heavier soldering iron of similar construction with 3 burner openings is shown in Fig. 3. The support 2' is provided with a slit 0 in order to adapt the iron to the varying gas pressure by altering the dis tance between burner and copper piece.

Fig. 4 shows a heavy soldering iron with six burner openings arranged in two rows. The copper piece, of square section, is supported by two pillars 2'. The burner piece 7) contains the necessary holes to conduct the gas to the six burner openings.

Fig. 5 represents a small soldering iron of pointed shape and square section with one flame.

For many purposes stationary soldering irons are wanted. In this case the tube i may be connected rigidly with the gas supply.

While the preferred embodiment of the present invention has been specifically illustrated and described, it is to be understood that the present invention is not limited to the illustrated embodiment but may be embodied in other constructions of soldering irons for gas within the scope of the invention as particularly pointed out in the following claims.

hat I claim as my invention is:

1. In a soldering implement, a metal burner member formed with an internal passage to receive a supply of illuminating gas, said passage terminating in an opening; and a burner tip of refractory material seated in said opening and formed solely with two diverging internal, gas-receiving apertures opening at their outer ends through the inner face of the tip, and two oppositelylocated, converging holes of appreciably smaller diameter than said apertures leading from the inner ends of the latter and opening in extremely close relation to each other at their outer ends through the outer face of said tip, whereby the burning gases issuing through said converging holes will impinge against each other and unite in forming a thin, fiat flame which is nonluminous and extremely hot.

2. A burner tip of refractory material for gas-heated soldering implements, formed solely with two diverging internal, gasreceiving apertures opening at their outer ends through the inner face of the tip, and two oppositely-located, converging holes of appreciably smaller diameter than said apertures leading from the inner ends of the latter and opening in extremely close relation to each other at their outer ends through the outer face of said tip, whereby the burning gases issuing through said converging holes will impinge against each other and unite in forming a thin, flat flame which is non-luminous and extremely hot.

3. In a soldering implement, a metal burner member formed with an internal passage to receive a supply of illuminating gas, and with a plurality of parallel, longitudinal rows of openings with which such passage communicates, the openings in the several rows being arranged in transverse alinement; and a burner tip of refractory material seated in each opening, each tip being formed solely with two diverging internal, gas-receiving apertures opening at their outer ends through the inner face of the ti), and two oppositely-located, converging holes of appreciably smaller diameter than said apertures leading from the inner ends of the latter and opening in extremely close relation to each other at their outer ends through the outer face of said tip, whereby the burning gases issuing through said converging holes will impinge against each other and unite in forming a thin, flat flame which is non-luminous and extremely hot.

In testimony whereof I afiix my signa' ture.
